![]() Encapsulate kmalloc vs vmalloc memory allocation and freeing logic into two helpers, ceph_kvmalloc() and ceph_kvfree(), and switch to them. ceph_kvmalloc() kmalloc()'s a maximum of 8 pages, anything bigger is vmalloc()'ed with __GFP_HIGHMEM set. This changes the existing behaviour: - for buffers (ceph_buffer_new()), from trying to kmalloc() everything and using vmalloc() just as a fallback - for messages (ceph_msg_new()), from going to vmalloc() for anything bigger than a page - for messages (ceph_msg_new()), from disallowing vmalloc() to use high memory Signed-off-by: Ilya Dryomov <ilya.dryomov@inktank.com> Reviewed-by: Sage Weil <sage@inktank.com> |
